Can comets create a microclimate crater on Mars 30km deep with 0.7bars?

[QUOTE="Vanadium 50, post: 6840511, member: 110252"] Well, it's probably calcuable numerically, but I sure wouldn't want to propose it. I can hear the laughter now. We can look at impacts in the solar system and we have our answer. [LIST] [*]No impact has left a crater this deep [*]The OP doesn't just want "deep", he wants "small" (or "narrow") and deep craters are large - and get a lot larger and only a little deeper. [*]We have evidence of impacts that have severely disrupted the target body - Mmas, Vesta - and they don't leave craters this big. Increase the impactor's energy and you don't get a bigger crater; you get more asteroids. [/LIST] [/QUOTE]
